2-Decarboxy-2-hydroxymethyl-trans-2,3-didehydro-9-deoxy-9-methylene-PGF compounds

ABSTRACT

The present specification relates to novel 9-deoxy-9-methylene-trans-2,3-didehydro-PGF compounds with improved pharmacological properties. While these compounds are useful in inducing a wide variety of prostaglandin-like pharmacological effects, they are specifically useful as regulators of procreation and fertility.

The present application is a divisional application of Ser. No. 893,771, filed Apr. 5, 1978, now U.S. Pat. No. 4,165,436, issued Aug. 21, 1979.

The present invention relates to prostaglandin analogs, for which the essential material constituting disclosure therefor is incorporated by reference here from U.S. Pat. No. 4,165,436. 

I claim:
 1. A prostaglandin analog of the formula ##STR1## wherein Y₁ is trans-CH═CH-, -C.tbd.C-, --CH₂ CH₂ --, or cis-CH═CH-;wherein M₁ is ##STR2## wherein R₅ is hydrogen or methyl; wherein L₁ is ##STR3## wherein R₃ and R₄ are hydrogen, methyl, or fluoro, being the same or different, with the proviso that one of R₃ and R₄ is fluoro only when the other is hydrogen or fluoro; wherein g is 4, 5, or 6; wherein R₇ is ##STR4## wherein h is zero, one, two, or three, wherein m is one to 5, inclusive, T is chloro, fluoro, trifluoromethyl, alkyl of one to 3 carbon atoms, inclusive, or alkoxy of one to 3 carbon atoms, inclusive, and s is zero, one, 2, or 3, the various T's being the same or different, with the proviso that not more than two T's are other than alkyl, with the further proviso that R₇ is ##STR5## wherein T and s are as defined above, only when R₃ and R₄ are hydrogen or methyl, being the same or different.
